Panel charge not dependent on incident light angle
Closed, ResolvedPublic


At the moment, time of day is the only apparent determining factor for solar panel charge. I should be rewarded for considering incident angle on the panels when I am charging or roving, to pick better strategies for energy management.

When roving into a crater with the sun behind the rover:

  • Base charge is e.g. 6W
  • On entering the crater, rover nose dips down, and sunlight is more oblique, so charge should decrease, e.g. 4W
  • Driving up the far side of the crater the sun approaches the panel's normal, so charge should increase e.g. 10W

All driving at a particular time of day generates the same charge, even when panels are pointed further than 90 degrees from sun (steeply driving down can place sun under panels).
